Olerup QTYPE for pre-transplant matching is completed within an hour and is a robust and easy to use alternative for rapid HLA typing. The rapid matching provided by Olerup QTYPE is an important performance differentiator for pre-transplant matching of organ donors and recipients. This new test brings several needed features to HLA labs, including speed and enhanced resolution.

“Following a convincing demonstration of Olerup QTYPE, we are excited to be the first center to order the new HLA typing kits,” says Cathi Murphey, HLA Director at Southwest Immunodiagnostics in San Antonio.

"We just launched our HLA typing solution at the ASHI conference in September 2016. The rapid commercial conversion demonstrates the compelling performance of Olerup QTYPE and the innovation embedded in the technology," stated Peter Maag, President and CEO of CareDx. "For CareDx, it is one step further along our road to provide novel diagnostic solutions to improve the care of transplant patients across pre- and post-transplant continuum."
